About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X600S
The B04-SC40X600S is an AirTAC double-acting tie-rod pneumatic cylinder engineered for construction machinery. The B04- prefix designates it as the heavy-equipment dedicated variant of the standard SC40X600S, meaning it is mechanically identical to the base model with a 40mm bore and 600mm stroke.
Delivering 879N of push force at 0.7MPa (1130N at 0.9MPa), this unit features a 16mm piston rod, PT1/4 ports, and 21mm adjustable cushions. The S suffix indicates a built-in magnet for mounting CMSG or DMSG reed sensors along the 142mm body length.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X600S Is Used
Excavator Door Control
Actuates heavy cab doors on earthmoving equipment, utilizing the 600mm stroke to achieve full opening clearance.
Concrete Pump Positioning
Shifts discharge chutes or flow diverters on concrete pumps where the 879N output at 0.7MPa easily overcomes material resistance.
Crane Outrigger Locking
Drives secondary safety pins or alignment locks on mobile crane outriggers, relying on the magnetic sensor for position confirmation.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X600S the Right Cylinder?
This 40mm bore provides 628N push at 0.5MPa; step down to a 32mm bore for 402N if lower force is needed, or up to a 50mm bore for 982N for heavier loads. Because the 600mm stroke creates a long unsupported rod extension, use an external guide rail to prevent rod-bearing bending under side loads.
To replace this cylinder, match the 40mm bore, 600mm stroke, PT1/4 thread, basic mounting, and the built-in magnet. The SC is a tie-rod design and is shorter than an ISO 15552 cylinder, so verify body length dimensions before swapping.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC40X600S FAQ
The B04- prefix indicates this is AirTAC's construction-machinery dedicated variant. It is mechanically identical to the standard SC40X600S, offering the same 40mm bore, 600mm stroke, and 1130N thrust at 0.9MPa.
No, the adjustable cushion only decelerates the piston at stroke end and does not lock the rod. If a vertical load must be held without live air pressure, you must use an external mechanical lock or pilot-operated check valve.
